From 65a2ae8d5bd0ab9fb5846c0223d5dcf74e87f9d2 Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Fri, 28 Nov 2014 05:26:36 +0000 Subject: [PATCH] asm-generic: add generic seccomp.h for secure computing mode 1 Those values (__NR_seccomp_*) are used solely in secure_computing() to identify mode 1 system calls. If compat system calls have different syscall numbers, asm/seccomp.h may override them.
